Canine Hair Furnishings 1-2

Description:

The term "furnishings" refers to the longer moustache and eyebrows seen in dogs with wire hair, as well as some other breeds. Some breeds are fixed for this trait, such as the Airedale Terrier, which is known for their longer mustaches. However, in other breeds, this trait can be variable. In breeds such as the Portuguese Water Dog, furnishings can be variable. However, furnishings are required for a dog to adhere to the breed standard. In the Portuguese Water Dog, dogs without furnishings are referred to as having an "improper coat."

Furnishings are a dominant trait, meaning that a dog only needs to have one copy of the furnishings gene to show the physical trait. In order for a dog to display furnishings, the dog can either code as F/f or F/F. Dogs that are heterozygous (F/f) for the furnishings gene can pass on either the furnishings gene (F) or the non-furnishings gene (f) to any offspring. If two dogs are both heterozygous for furnishings, there is a 25% chance that each puppy could get the non-furnishings allele from each parent and not display that trait (f/f). This can make testing an important tool to be able to more accurately predict the type of coat of all the offspring being produced.

Improper Coat:

The breed standard for Labradoodle, Goldendoodles and Portuguese Water Dog requires “furnishings.” In these dog breeds, a lack of the dominant RSPO2 variant causes an improper coat, characterized by short hair on the head, face and legs.

Furnishings - 2

A novel Furnishings or Improper Coat variant (F2) was identified by Animal Genetics in several breeds of dogs. The mutation is recessive to the current RSPO2 variant (F1) but on its own causes a lesser form of furnishing. All requests for furnishings testing will include both F1 and F2 variants at no additional costs.

Hair Furnishings Testing:

Animal Genetics offers a test for the mutation that controls hair furnishings or Improper Coat. Dogs can be DNA tested at ANY age.

Sample Type:

Animal Genetics accepts blood, buccal swab and dewclaw samples for testing. Sample collection kits are available and can be ordered at Canine Test Now.

Testing Is Relevant for the Following Breeds:

Testing is appropriate for any type of dog suspected to have hair furnishings. Testing is recommended for the following breeds:

Results:

Animal Genetics offers DNA testing for dominant furnishings allele. The genetic test verifies the presence of the mutation and presents results as one of the following:

* Additional causes of this trait may exist. A negative result for this mutation does not eliminate the possibility that an additional, yet unidentified mutation or mutations in the genome may lead to a similar trait.

Furnishings1-2 / Improper Coat results:

F1/F1

Furnishings

The dog has two copies of the furnishings-1 allele. The dog will have furnishings, and will always produce puppies with furnishings. 2 copies of Improper Coat, dog has Improper Coat, dog will NOT have longer hair on the muzzle and eyebrows.

F1/n

Furnishings

Both the dominant and recessive alleles are detected. The dog will have furnishings, and carries the allele for no furnishings. The dog can pass on a copy of either allele to any offspring. 1 copy of Improper Coat, carrier, dog will have longer hair on the muzzle and eyebrows.

n/n

Non-Furnishings

The dog is negative for the furnishings-1 variant. The dog will have no furnishings, and will always pass on the allele responsible for no furnishings to any offspring.
No copies of Improper Coat, normal, dog will have longer hair on the muzzle and eyebrows.

F2/F2

Furnishings

The dog has two copies of the furnishings-2 allele. The dog will have minimal furnishings, and will always produce puppies with come furnishings.

F2/n

Furnishings

Both the dominant and recessive alleles are detected. The dog will have furnishings, and carries the allele for no furnishings. The dog can pass on a copy of either allele to any offspring.

n/n

Non-Furnishings

The dog is negative for the furnishings-2 gene. The dog will have no furnishings, and will always pass on the allele responsible for no furnishings to any offspring.
No copies of Improper Coat, normal, dog will have longer hair on the muzzle and eyebrows.

F2/F1

Furnishings

The dog has one copy of furnishings-2 and one copy of furnishings-1 allele. The dog will have normal furnishings, and will always produce puppies with some level of furnishings.
